The already included, basic software of the MarPrime System requires no additional installation of pick-up sensors or crankshaft position transmitters and will carry out the TDC correction of the pressure sequences automatically.

Based on the measured pressure curve and the TDC correction further parameters like mean indicated/ effective pressure, compression pressure and engine power will be calculated. The most important process parameters (such as maximum pressure, average indicated pressure, compression pressure and engine output) are displayed in the form of graphs, bar charts and statistics. Report functions are also provided.

All thresholds can be customized according to which engine you deploy, and by clicking only one button, you will get an immediate overview of the entire engine process. Measurement information provided by MarPrime System can be used for:

  • Optimizing the engine operation
  • Monitoring the load balance
  • Checking the valve timings
  • Reducing fuel consumption and emissions
  • Determining condition of the cylinder head assembly
  • Reducing costs of replacement parts and maintenance
